UIJCOUIPLING ATTACHMENT.

Application filed Apri129 1911.

To all whom it may concern Be it known that l, lViLLmn J. Knox, a citizen of the United States, residing at Dubois. in the county of Clem-field and State of Pennsylvania, have inventeol certain new and useful improvements in Uneoupling Attachments, of -which the follow ing); is a specification.

The invention relates to uncoupling attachments or rigging for use with the automatic couplers employed upon railway cars. I

The primary objects of the invention are: the provision of an improved and positi e form of flexible connection wherein the use of chains, loose links and similar devices is avoided; the provision of .an uncoupling device capable of use with the brackets now en'iployecl with olol anrl unsatisfactory forms of rigging; the provision of an uncoupling device which may be formed of common bar iron. or steel so simply manufactured anti assembled that highly skilled labor is not required; and the provision of apparatus in which the rigging may be detached from the'coupler Without detaching the brackets carrying the rigging.

Jertain embodiments of the invention are illustrated in the accompanying drawings. u'herein:-

Figure 1 is a plan View of the attachment as applied to a car; Fig. 2 is an owl eleva tion oi the amiaratus shown inl ig. 1;'

l is a perspective View of the operating rod employed in Figs. 1 and 2; 4t, 5,

ancl ii are detail views oi? modified-form of opeiating rocl; Fig. 7 is a plan. view. of

another form of the apparatus as aplplieol to a. car; 8 a side elevation of the at taclnnent shown in Fig. 7 9 is a seotion through the rock shaft of Fig; '3' anti. shows an entl elevation of the operating roci shown in such figure; Figs. 10 and it are plan and sicle elevation views respectively of another embodiment of the invention.

lfleferring to l 9; and 3, l is the cow pier head, provided with usual vertically movable pin is what may be termed the operating rod; i is What may he termetl the melt shait; and 5 and 6' are brackets upon the curl of the car for supporting the rock shaft. The end of the operating ro i 3 xtends slirlably through the head ofthe pin 2 and is provided with a bend 2' for me venting the accidental detachment of the Specification of Letters Patent.

rod from the pin. The other end of the operating rod is bent at 8 and is provided \\'ith a loop 9 encircling the end of the arm 10 of the rock shaft, such arm 10 being provided with a bend 11 at the point of en gagement with the loop 9. The arm 10 bends down below the plane of the body of the rock shaft 4 as indicated in Fig. .2, the bend 11 and extreme end of the rock shaft lying belo'u the rod 3. The other end of the rock shaft 4 is provided with the usual The rotation of the shaft 4: lifts the end of the arm 10. anti because of the loop conneetirn anti the fact that the end of the arm 10 passes untler the rod 3, such rod 3 is raised, thereby lifting the pin The arrangement provides for positive connection between the rock shaft and op erating rod, and at the same time provides connection which is entirely flexible, the connection between the loop 9 and bencl 11 giving substantially a universal joint. The l0(.l 3 slides freely through the pin 2, that the coupler head can move a consider able distance in any direction Without causing any strain upon the uncoupler rigging or Without binding in any way. The bend ll prevents the loop 9 from slipping oil the arm 10 enclwise. It will be seen that the construction is a simple one, and one that may be readily formed Without machine Work. from ordinary bar iron. If desired, the shaft 4.- ma y be extended so as to be on emble from the other side of the car.

in orrler to permit the ready removal of the operating; rod from the roclrshaft. arrangement shown in l. 5 and 6 is preferably used, the only tlillerence of con struetion in the operatirur rorl 3 there used over that of the operating rod 3 of Figs. 1 and it being in the fact that the loop 9' is motlereaolily detaehably by leaving open. one side, indicated? in Figs. 5 anal anti pro-- irling a removable cotter pin 1395.01 closing snob. open side, lit will be seen that this constitutes a cheap l w' avenient v.rn'eans for pro'virling a detach ole eolnnectioen so that the operating roc'l may be rlisenga "eel When it is desired to remove the coupler howl, such arrangement obviating the neccs sity of providing for the removal of the rock shaft/l.

somewhat clilferent arrangement is shown. in Figs. 7, 8 and 9. In this construction the operating rorl 14 is providecl AWllZll an open sided loop 15 closed by the cotter pin 16, and this loop engages a'bend 17 in the rock shaft 18, the end of such rock shaft crossing the operating rod 14: as in the form 10f device previously described. The advantages of this form of construction are substantially the same as those a pointed; outwith respect to the construction shown in Figs. 1 to In-Fi'gs. l0 and 11 sttll :another form of construction is shown, operating rod 19 bein bent at 20 in the rev rse direction and provided with a loop 21 engaging the upturned end 22 of the rock shattZl-l. This arrangement also provides for free relative movement between the operating rod and rock shaft,'and yet prevents the accidental -disengagement' of the two members.

an operating rod having one leg extending shdably through the head of the pin andthe other leg bent at an angle to such first leg, and provided with a loop,'and a rock shaft having its body portion supported for rotary movement and having one end bent at substantially right angles to the body portion and crossing the operating rod, the rock shaft being provided adjacent its end with a. bend engaged bythe said loop in the operating rod.

2. An uncoupling attachment, comprising a rock shaft having its inner portion bent laterally 'and such inner portion provided with a bend adjacent its end, an operating rod having one end extending slidably through the head of the pin and the other end bent laterally in substantially a horizontal plane with an open sided loop at its extremity embracing the said bend i the rock shaft, and a removable pin for c osing the side of the said loop, the inner end of the said rock shaft being positioned SOIRS to engage the operating rod andl lift it.

In testimony whereof I have hereunto signed my name in the presence of the two subscribed witnesses.
